BELT-LACING TOOL.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application filed December 26, 1908. Serial No. 469,486.

To all whom it may concern:

Be it known that I, HARRY THOMAS MUM- roRD, a subject of the King ofEngland,'and a. resident of New York, county and State of New York, haveinvented certain new and useful Improvements in Belt-Lacing Tools andSquares, of which the following is a full, clear, and exact description.

This invention relatesI more particularly to a tool for forming ametallic lacing on each end of a belt.

The primary object of the invention is to provide a simple and efficienttool which may be cheaply made and which is so formed that the tool maybe readily placed over the end of the belt and held in position to forma guide for the metallic wire employed a lacing, and to arrange thelacing in the form of a spiral the convolution of one end of j the beltbeing opposite to that of the other end to adapt the same to beinterlocked and held together when the ends of the belt are brought inclose relation to join its ends.

Another object of the invention is to provide a device which may beemployed as a square to trim the edge of the beltproperly it'or lacingor for other purposes.

A further object of the invention is to provide a device which may bemade out of sheet metal, which is adapted to hold the lacing properlyuntil it is formed in the required shape, and which permits the tool tobe shifted without removing the usual forming mandrel.

YWith these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawingswhich form a part of this specification, and will then be pointed out inthe claims at the end of the description.

ln the drawings, Figure 1 is a plan view of one form of device embodyingmy invention. Fig. 2 is an end elevation of the tool as applied to oneend of a belt. Fig. 3 is an end view of the device showing the lacing inthe course of being made; and Fig. 4 is a plan view showing the ends ofthe belt properly laced and held together.

The tool has a substantially rectangular body portion 11 provided withopenings 12 whereby the tool may be temporarily fastened by rivets 13,orotherwise, to the end of the belt B, and said tool may be made of asingle sheet of brass, steel or other material. The ends o'f the bodyportion 11 may extend inward, as at lt and 15, to provide a space 16 and17 between said ends into which the end of the belt to be laced isadapted to lit.

The ends are curved at 16a and 17 respectively, and the body, in endview, is substantially S-shaped in form. The ends 16a and 1Td of thetool have angularly arranged guides 18 for the lacing and said guidesare spaced to provide slots or spaces 19. These guides, as well as thespaces 19 are substantially V-shaped when viewed in plan, and one arm,20, of each of the guides in theI body portion at an angle with respectto the arm 21 on the inturned parts lll and 15. The entire tool may becast or otherwise formed instead of being made of sheet metal, and theslots and guides in the end 16 are oppositely arranged to t-he guidesand slots in the end 17, so that when the lacing is properly made theywill be disposed with relationv to each other as shown best in Fig. 4A.The guides 1S in the ends of the tool are substantially V-shaped in edgeview, and form loops to cause the wire while making the lacing to assumea helical form.

A mandrel 22 is placed between the inner surface 23 of the guides 18,and this mandrel used to form the ends of the lacing and to determinethe distance the lacing is to project beyond the end of the belt, thoughwhen the lacing is made on wide belts, I may profor to use at least twomandrels which may be D-shaped in order to be easily withdrawn and avoidpulling the lacing out of its proper shape, and to keep two or moremandrels in position they may be fastened at one or both ends by meansof pins or any other suitable means. By making the tool on the formshown, the said tool is adapted to be shifted transversely of the beltwhere wide ones are to be laced without removing the mandrel, and whenthe lacing is started, it is of course understood that the end of thewire is fastened in any suitable way and after the lacing has been madethe end of the wire is also fastened in the belt end.

Vhen the two ends of the belt have been laced by the tool and the endsof the lacing properly fastened to the belt ends, the said ends may bebrought together and a rod or joining member 24: may be passed betweenthe interlocked ends held as best shown in Fig. 4f.

To permit the tool to be used as a square for trimming the ends of beltsor for other purposes, l malte the sides or edges 25 straight and atright angles to the inner surface 23, or the outer surface thereofaccording to the way it is used, so that it the tool is placed over theside edge ot the belt the sides or" the tool 25 will extend at rightangies to permit the ends ot the belt to be squared.

From the foregoing it will be seen that a simple and efficient tool ordevice is provided which is adapted for use as a square or to heemployed tor t'orining metallic lacing on the ends of belts; that saidtool simple in construction and niay be readily applied to the belt inposition tor lacing purposes; that said tool may be made of a singlepiece ot metal and has its ends so formed that both ends ot the belt maybe laced properly, and that said tool may be used tor lacing belts muchWider than the tool itself.

Having thus described my invention, l claim as new and desire to secureby Letters .Patent l. A tool et the character described, coniprising a.body portion having its ends provided with oppositely and inwardlyextendving parts, and with angularly disposed guides forming spacesbetween the same.

A tool of the character described` comprising a body portion having anend provided with an inwardly extending part, and with angularlydisposed guides forming spares between the saine.

25. A tool of the character desiaibed, comprising a body portion having`an end provided with an inwardly extending part spaced 'from said bodyportion tor the end oit the belt to be laced, and with angularlyarranged guides spaced apart and forming loops at the end for a mandrelto be seated between the body portion and said extendA ing part, thepart oi the guides on the extending part being at an angle with respectto the part on the body portion.

fl. A tool of the character described, com* prising a substantiallyrectangular body portion having .its ends provided with oppositely andinwardly extending parts, and with angularly disposed Ouides spacedapart and forming loops at said ends, the guides of one end beingoppositely arranged with respect to the other and the parts of theguides in the body portion being' at an angle to the parts in theinwardly extending parts.

5. A tool of the character described, Coniprising a substantiallyrectangular and S- shaped body having angularly disposed guides arrangedin the ends thereof.

G. A tool ot the character described, coinprising a substantiallyS-shaped body portion having angularly and oppositely disposed spacedguides arranged in the ends thereof.

7. A belt lacing tool having its body portion provided with guides atone end which are spaced apart so as to form loops for the reception ofa mandrel and the end of the belt "to be laced.

8. A. tool ot the character described, comprising a body portion havingan end provided with an inwardly extending part and angularly disposedguides in said end, the said body portion having an edge at right anglesto the inwardly turned part to adapt the saine to be employed as asquare.

9. A tool oit the characterdescribed, coniprising a body portion havingits ends pro vided with inwardly extending parts and angularly disposedguides forming loops in said ends, the said body portion having itsedges at right angles to the inwardly turned parts to adapt the same tobe employed as a square.

l0. A tool of the character described, comprising a body portion havingits ends substantially U-shaped in which the end of a belt is adapted tobe inserted` and forming a space in which a mandrel may be readilyinserted and removed, said ends being provided with substantiallyU-shaped and spaced guides for the lacing and extending entirelythrough. said ends of the tool.

ll. A tool of the character described, comprising a body portion havingits ends substantially U-shaped in which the end ot' a belt is adaptedto be inserted and forming a space in which a mandrel may be readilyinserted and removed, said ends being provided with substantiallyU-shaped and spaced guides for the lacing, said guides eX- tendingentirely through said ends of the tool and angularly arranged withrespect to said ends.
